Kekkon shimashou, Yamome-san

Masami Yamome is a 39-year-old divorcee. He's just a typical middle-aged man with a typical office job. The young man he runs into one day is the unbelievably handsome Iha Nishijima. Ever since the first time they meet, Masami feels like he's been thrown into a whirlwind relationship. First, Iha tells him that he's into men and then asks him to marry him! Iha further suggests living together and trying to take their relationship to the next level and it's all too much for Masami!! Iha looks like a dashing gentleman and he has great business acumen, but everything he says and does is completely outrageous! A relationship that starts with one man asking a straight man to marry him!
